\ FOOD-CHOPPER.

Specification of Letters Patent.

Patented Oct. 16, 1 906.

Application filed January 30. 1901. Serial No. 45,325.

To all whom it may concern:

Be it known that I, JOHN H. SHAW, of the city and county of New Haven,State of Connecticut, have invented a new and useful Improvement inFood-Choppers, of which the following is a full, clear, and exactdescription when taken in connection with the accompanying drawings,which form a part thereof, and in which Figure 1 represents a centrallongitudinal section through the horizontal cylindrical casing of thechoper; Fig. 2, a transverse vertical section on lines 2 2 of Fig. 1;Fig. 3, a view similar to Fig. 1, showing in addition the screw-likeforcer and cutters at the forward end thereof; and Fig. 4, an end viewof the forcer and blades thereof.

In all figures similar letters of reference represent like parts.

This invention relates to food-choppers; and it consists in the novelrelation between the feeding-ribs within the horizontal cylin dricalcasing and the cutting-arms at the forward end of the casing, as setforth in the construction and combination of parts described and claimedhereinafter, whereby a continuous free passage for the meat or otherfood operated upon is obtained through the cylindrical casing andpreliminary cutters to the outer cutters along the principal lines ofmovement or. channels between the ribs.

The invention is shown applied to a foodchopper of the type described inthe United States Patent No. 623,839 granted to me on the 25th day ofApril, 1899, to which reference may be made for a more detaileddescription of some of the parts.

Referring to the drawings, the parts designated by the letter Arepresent the horizontal cylindrical casing through which the food isforced after being fed into the hopper B, extendingupward from thecasing.

C represents a portion of the legs or stand.- ard for supporting thecasing.

D represents spiral feeding-ribs projecting inwardly from the interiorsurface of the casing, forming channels between them, along which thefood may be forced, and E represents radial cutting-arms formed integralwith-the forward end of the casing and the inner ends of which terminatein a bearingring F, concentric with the casing A. Each cutting-arm Eprojects inwardly from the forward end of one of the feeding-ribs D, so

that each of the ribs terminates in a cuttingarm, leaving the channelbetween the feedingribs unobstructed from end to end.

G represents the screw-like forcer for forcing the meat along thechannels between the ribs. The forcer G terminates in blades orknife-edges H at its forward end, which form with the inner faces of thecutting-arms the preliminary cutters or shears of the chopper, by whichat least a partial cutting orsevering is produced in the meat.

As shown in Figs. 1, 2, and 3, the inner faces or operative surfaces 6of the cuttingarms E are limited by the inward projection of thefeeding-ribs and are therefore shorter than the outer faces 6 of thearms, which extend from the bearing-ring to the inner surface of thecasing. The forcer G and knives H are of substantially the same diameterand are rotated by the handle I within the feeding-ribs in the casing.The diameter of the forcer and knives is as much less than the internaldiameter of the casing as the feedingribs project inwardly from theinternal surface of the casing, "as shown in Fig. 2. The knives Htherefore, as shown in dotted lines in Fig. 2, upon their rotation comein contact with substantially the entire inner face or operative surface6 of each ofthe cutting-arms, but do not extend entirely across thechannels between the feeding-ribs D and arms E. At the forward end ofthe forcer beyond the knives H is an axial bearing K, adapted to fit androtate within the bearing-ring F. For.- ward of the bearing K is amounting L for the rotary perforated disk or outside cutter M, which maybe of a construction similar to that shown in my former patent, alreadyalluded to, and which therefore needs no de tailed description herein.The forcer finally terminates in a screw-threaded portion N for thereception of a nut 0, adapted to bind on the cutter M and hold the partstogether. As shown in Fig. 3, the perforations m of the outside cutter Mmay extend radially to the farther end of the outside operative surfaces6 of the arms E, and therefore extend across the entire channels betweenthe ribs. By this construction there is no obstruction to the passage ofthe meat within the channels between the ribs until the outside cutteris reached, except so far as the knives H in their revolution passacross the inner portions of the channels and tend to sever the meat incontact with the inner faces e of the arms E.

' Having now described my invention, which may vary in itsdetailswithout departing from the spirit thereof, what I claim, and desire tosecure by Letters Patent, is

In a food-chopper, the combination with a substantially cylindricalcasing of continuous spirally-arranged feeding-ribs within said casingextending to the outlet therefrom and terminating each in a cutting-armextending laterally of the casing, said cuttingarms being of a width nogreater than the width of the ribs, whereby a plurality of continuousunobstructed passages are formed between the ribs and arms to theeitterior of the casing, and a screw-like forcer arranged. within thecasing and provided at one end with a blade or blades arranged tocooperate with the inner faces of said cutting-arms.

In witness whereof I have hereunto set my hand this 24th day of January,1901.
